To actually do the volumes that make pumped hydro practical you need not just a hill but a space which can hold a truly huge volume of water.
Yeah pumped hydro needs lakes, not pools, as far as I know. They flood entire mountain valleys, using the surrounding mountains themselves as the storage structure, because they need so much space.
But a warehouse-sized balloon works?
Yes, because phase transitions involve absolutely huge amounts of energy.
